Definitions

  • the invention relates to the products and process as per the first portion of the independent claims.
  • TTCN Testing and Test Control Notation
  • SIP Session Initiation Protocol
  • VoIP Voice over IP
  • DMR Digital Mobile Radio
  • HiperMAN WiMax
  • IMS 3GPPTM IP Multimedia Subsystem
  • US 2014/033175 A (LEE CHUNG-I [TW] ET AL) 30.01.2014 discloses a computer-implemented method comprising defining user requirements for testing a software program, syntax keywords of a test script, and a test template for creating test cases driven by the keywords.
  • WO 2007/137082 A (CAPTARIS INC [US]; ROTH RICK R [US]) 29.11.2007 discloses a wizard.
  • CN 102929680 A (ISOFT INFRASTRUCTURE SOFTWARE CO., LTD) 13.02.2013 discloses a method, a device and a system for converting a TTCN-3 script into a Java source code to compile the TTCN-3 script.
  • a translator of the TTCN-3 script is constructed, analyzes and verifies a test object file, and then translates the TTCN-3 script into a Java file according to predefined translation rules.
  • a Java runtime support library is constructed according to the translation rules of the translator, supports the foundation classes quoted in a translation scheme, and completes the execution of the code generated by translation and the recording of the execution results.
  • the complete Java source code in accordance with a TTCN-3 semanteme can be acquired through the integration of the code translated by the translator and the code of the runtime support library.
  • Keyword-driven testing is a test case specification approach that is commonly used to support test automation and whose fundamental idea is to provide a set of building blocks - referred to as keywords - that may be used to create manual or automated test cases without detailed knowledge of programming or test tool expertise. Keyword-driven testing aims to provide a basic, unambiguous set of keywords comprehensive enough so that most, if not all, required test cases can be entirely composed of said keywords.
  • the vocabulary included in these dictionaries or libraries of keywords is, therefore, a reflection of the language and level of abstraction used to write the test cases and not of any standard computer programming language. Practical applications may be gathered from HAMETNER, Reinhard, et al. Agile testing concepts based on keyword-driven testing for industrial automation systems. IECON 2012 - 38th Annual Conference on IEEE Industrial Electronics Society. 25.10.2012, p.3727-3732 .
  • the invention combines established syntax rules with an innovative approach to the semantics of specifications without degrading their readability.
  • the method (10) illustrated by Figure 1 extends upon the concept of keyword-driven testing by making a general proposal for the realization of the keywords, which in this context are referred to as "phrases". Using these phrases, system states, signals, activities, sequences of actions, etc. can be described easily and clearly.
  • the outlined approach is not limited to creating test specifications (12) but may equally be applied to the specification of requirements (11). Its focus is on readability and ease of use, allowing for the method (10) to be employed directly and efficiently without extensive training or expertise.
  • the proposed notation differs from formal languages in that the vocabulary is unrestricted and may be extended by any user. This creates a living language that constantly evolves and improves.
  • An underlying database (18) can be filled with any keywords including their corresponding translation into multiple domains (13, 14, 15).
  • Such domains (13, 14, 15) might include, for example, hardware or software "in the loop” (13), vehicle driver instructions (14), messaging (15) over a signal network such as Flexray or Ethernet, or system state.
  • a phrase optionally comprises a class (e. g., "state”, “coding”, or “parameters”), system (e. g., a specific control unit or “vehicle”), and argument (e. g., the value of a variable).
  • a fully qualified phrase takes the following form: "Class::System::KeyWord[Argument]”.
  • a desired steering angle to be retained as a coding value may be described as follows: "Coding::EPS::SteerAngleThreshold[20°]".
  • EPS electrical power steering
  • the repository (18) created throughout the specification phase can be easily distributed across project teams, departments, and external cooperation partners along with the actual specification (12). It essentially defines a meta-model, allowing for the concrete syntax and semantics to be adapted to project-specific requirements.
  • test case (16) may be regenerated "at the push of a button" without introducing significant time delay or resource cost.
  • the inventive method (10) further supports assessing the quality of requirements (11) and test specifications (12). Based on the syntax and semantics of the proposed language, key performance indicators (KPIs) for evaluation can be defined. This aids users in optimizing specifications (12), avoiding inconsistencies, and managing the overall project according to its established project status.
  • KPIs key performance indicators
  • requirements entirely composed of known phrases may be defined as high-quality; requirements only partly composed of known phrases may be considered in need of improvement; and requirements devoid of known phrases may be attributed a low or unknown quality.
  • the repository contains comprehensive definitions for all those parameters and, on the other hand, that no parameters remain unused throughout the specification in its entirety.
  • An embodiment of the invention significantly simplifies those processes, allowing small changes to a requirement (11) to reflect in the test specifications (12) and test cases (16) without delay.
  • the keywords can be translated into various domains (13, 14, 15), such as from a general test specification (12) into hardware or software "in the loop” (13), driver instructions (14), or bus messaging (15). With manual conversion into these individual domains (13, 14, 15) thus becoming obsolete, costs may be saved, mistakes avoided, and development dynamics increased.
  • test script implementation can be standardized, programming rules defined, and commentary added automatically.
  • bidirectional traceability between test specification and test implementation may be automated.
  • each phrase can be customized using further attributes such as descriptions or search terms.
  • an autocomplete tool connected to the database (18) makes it easy to find the correct keyword.
  • the phrases, upon the keywords having been entered, are parameterized by means of a software wizard.
  • a preferred embodiment provides a search function for phrases and examples of their application. After specifying the requirements (11), the wizard automatically transfers any new requirement (11) to the target application and stands by until being invoked again using a convenient key combination. However, the use of tooling remains optional, permitting each user to decide for herself how to enter phrases.
  • the invention is applicable, inter alia, throughout the electronics, software, and automotive industries.
